Outdoor security cameras have become necessary to our lives to deal with traffic management and security maintenance in modern society. If you look closely, you can see that these security cameras can be seen almost everywhere on the streets, whether you’re in a big city or a small town. Also as smart homes have become more prominent, the popularity of security cameras has been increasing alongside.
The increasing consumer demand for security cameras has prompted many manufacturers to invest in these products. Usually, each manufacturer will set requirements for product verification and testing. However, these requirements are starting to get less strict, allowing for more issues to occur with these products.
Product reliability verification is more time-consuming compared with general product quality verification. Manufacturers try to reduce reliability testing due to a lack of patience and trying to seize market opportunities. Long-term testing like high-temperature and high-humidity testing is usually overlooked. This can lead to some serious risks down the line.
What Are Tin Whiskers?
Tin whiskers or metal whiskering is a type of “stress relief”. When the surface of solder is in contact with various organic substances such as oxygen, sulfur, carbon, and others, it compresses the composition of the tin and generates internal stress. When it is relieved, the tin atoms will be expelled outwards, forming whiskers.
Recently, lead-free solder has replaced traditional solder that contains lead due to environmental issues. Lead-free solder contains over 95% of pure tin. The problem is that the more tin, the easier it is for the metal to produce whiskers. The main factors that affect the growth of tin whiskers are temperature and humidity.
Potential Risk of Causing Failure to Electronic Products
If the whiskers grow too long and connect two pins, it can cause transmission failure, short-circuiting, or even product damage.
